Top Stories - incorrect documentation and no results

[MrZANO]

Goodmorning everyone,
I point out that the documentation is wrong, there are no brackets ")" and the array management is incorrect
$newsTitle = $title;
to
$newsTitle = $news->title;
the complete code generated by me to get the results of the word "homicide" is as follows

if ($result->is(NaturalResultType::TOP_STORIES)) {
                foreach ($result->news as $news) {
                    if ($news->is(NaturalResultType::TOP_STORIES_NEWS_CAROUSEL)) {
                        // carousel
                        $newsTitle = $news->title;
                        $newsUrl = $news->url;
                        echo "TOP_STORIES_NEWS_CAROUSEL-->" . $newsUrl . " " . $newsTitle;
                    } elseif ($news->is(NaturalResultType::TOP_STORIES_NEWS_VERTICAL)) {
                        // vertical
                        $newsTitle = $news->title;
                        $newsUrl = $news->url;
                        echo "TOP_STORIES_NEWS_VERTICAL-->" . $newsUrl . " " . $newsTitle;
                    }
                }
            }

ma nonostante ci siano "top stories" in SERPs non ottengo mai il parser dei risultati (bug?)
